Description

[[Technical Field]]

[0001] The present invention relates to a communication terminal and an information processing method. [[Background Art]]

[0002] In recent years, services that realize wireless communication using satellite stations, which are satellites that function as base stations for wireless communication, have been provided (see, for example, Patent Document 1). [[Prior Art Literature]] [[Patent Literature]]

[0003] [[Patent Document 1]] Japanese Patent No. 7662911 [[Summary of the Invention]] [[Problem to be Solved by the Invention]]

[0004] Since a satellite station orbits the Earth, the position of the satellite station changes as time passes. Therefore, even when a user's communication terminal does not move, the communication quality when the user's communication terminal communicates with the satellite station changes as time passes. For example, even when a communication terminal is in a state where it cannot communicate with a satellite station, communication may become possible as time passes. However, the user cannot recognize that communication has become possible, and it cannot be said that the convenience for the user when communicating using satellite communication is high.

[0005] Accordingly, the present invention has been made in view of these points, and an object of the present invention is to improve user convenience when communicating via a satellite station. [[Means for Solving the Problem]]

[0006] A communication terminal according to a first aspect of the present invention includes: a receiving unit that receives a data transmission request via a satellite station from a communication terminal that is not connected via a ground station but is connected via a satellite station; an acquisition unit that, when the receiving unit has received the transmission request and is unable to transmit the data via the satellite station, acquires information indicating the timing at which the communication terminal can transmit the data via the satellite station, based on the time change in radio wave conditions, which are the conditions of the radio waves received by the communication terminal from the satellite station; and a notification unit that notifies the communication terminal of guidance regarding the transmission of the data based on the timing information acquired by the acquisition unit.

[0007] The acquisition unit may acquire information indicating the timing based on the time change in the radio wave conditions that the communication terminal receives from the satellite station, which is determined based on the change in the position of the satellite station and the position of the communication terminal. The acquisition unit may acquire information indicating the timing based on the number of other communication terminals connected to the satellite station and the time change in the radio wave conditions received from the satellite station.

[0008] The receiving unit further includes a specification unit that identifies the amount of data corresponding to the transmission request received by the receiving unit, and the acquisition unit may acquire timing information by generating timing information based on the amount of data identified by the specification unit and the time change in radio wave conditions received from the satellite station.

[0009] The communication terminal further includes a specification unit that identifies the amount of data that the communication terminal can transmit via the satellite station at the present time based on the radio wave conditions, which are the conditions of the radio waves that the communication terminal receives from the satellite station, and the notification unit may notify information regarding the amount of data that the communication terminal can transmit via the satellite station at the present time.

[0010] The acquisition unit may acquire information indicating the timing when the receiving unit has received the transmission request but was unable to transmit at least a portion of the data via the satellite station.

[0011] The communication terminal may further include a transmission unit that, when the receiving unit receives the transmission request and is unable to transmit the data via the satellite station, identifies high-priority data included in the data and transmits the identified high-priority data via the satellite station. The acquisition unit may acquire information indicating a change in the area from which the data can be transmitted, as information indicating the timing at which the communication terminal becomes capable of transmitting the data via the satellite station.

[0012] A second aspect of the present invention relates to an information processing method which includes the steps of: receiving a data transmission request via a satellite station while the computer is not connected to a ground station but is connected to a satellite station; when the transmission request has been received but the data cannot be transmitted via the satellite station, acquiring information indicating the timing at which the computer can transmit the data via the satellite station based on the time change in radio wave conditions, which are the conditions of radio waves received by the computer from the satellite station; and notifying guidance regarding the transmission of the data based on the acquired information indicating the timing. [Effects of the Invention]

[0013] The present invention has the effect of improving user convenience when communicating via satellite stations. [Brief explanation of the drawing]

[0014] [Figure 1] This is a diagram illustrating the overview of a communication terminal. [Figure 2] This diagram shows the functional configuration of a communication terminal. [Figure 3] This figure shows an example of instructions regarding data transmission being displayed on the display unit. [Figure 4] This is a flowchart illustrating an example of the processing flow in a communication terminal. [Modes for carrying out the invention]

[0015] [Overview of Communication Terminal 1] Figure 1 shows an overview of communication terminal 1. Communication terminal 1 is a portable computer, such as a smartphone or tablet, used by the user, capable of wireless communication with ground station 2 and satellite station 3. Ground station 2 is a base station for wireless communication or telephone lines, etc., located on the ground. Satellite station 3 is a low-Earth orbit satellite, such as STARLINK®, that functions as a base station for wireless communication such as internet lines. If communication terminal 1 cannot establish a communication connection with ground station 2, it will connect with satellite station 3 via direct to cell (D2C) communication.

[0016] The communication terminal 1 is assumed to have an application program installed that corresponds to the function of communicating via the ground station 2 and an application program that corresponds to the function of communicating via the satellite station 3. The function of communicating via the ground station 2 is, for example, a function that consumes a large amount of communication bandwidth by sending and receiving data above a predetermined threshold or data that requires real-time processing. The function of communicating via the ground station 2 is, for example, a function related to voice calls using LTE (Long Term Evolution), video calls, live streaming, online screen sharing, streaming playback of high-resolution video, automatic synchronization to cloud storage, and a messenger function that can send data above a predetermined threshold. The function of communicating via the satellite station 3 includes the function of communicating via the ground station 2 and the satellite station 3. The function of communicating via the satellite station 3 is a function for transmitting and receiving data with a data capacity smaller than a predetermined threshold, and asynchronous or low-frequency data. The function of communicating via the satellite station 3 is, for example, a function related to a call using VoIP (Voice over Internet Protocol) and a messenger capable of transmitting data smaller than a predetermined threshold. The function related to the messenger only needs to mainly transmit and receive text information, and includes, for example, SMS (Short Message Service) and RCS (Rich Communication Services) that perform transmission and reception based on telephone numbers, and instant messaging applications provided by a specific operator.

[0017] In the present embodiment, the communication terminal 1 accepts a data transmission request. The communication terminal 1 accepts a data transmission request when it is not communicatively connected to a communication destination server or the like via the ground station 2, but is communicatively connected to the server or the like via the satellite station 3. When the communication terminal 1 has accepted a data transmission request and fails to transmit data via the satellite station 3, the communication terminal 1 acquires information indicating the timing at which the communication terminal 1 becomes capable of transmitting data via the satellite station 3 based on a temporal change in radio wave conditions, which are the conditions of radio waves received by the communication terminal 1 from the satellite station 3.

[0018] Then, the communication terminal 1 notifies guidance regarding data transmission based on the acquired information indicating the timing. With this configuration, when data transmission via the satellite station 3 fails, the user can check the guidance and determine when to retransmit the data. Therefore, the communication terminal 1 can improve user convenience when communicating via the satellite station 3.

[0019] [Functional Configuration of Communication Terminal 1] Next, the functional configuration of the communication terminal 1 will be described. Figure 2 is a diagram showing the functional configuration of the communication terminal 1. The communication terminal 1 includes an operation unit 11, a display unit 12, a communication unit 13, a storage unit 14, and a control unit 15.

[0020] The operation unit 11 is an operation device that receives user operations, and is, for example, a button provided on the communication terminal 1 or a touch panel provided on a surface of the display unit 12. The display unit 12 is a display that displays various types of information. The display unit 12 displays various screens under the control of the control unit 15. The communication unit 13 is a communication interface for transmitting and receiving data to and from a server or the like via the ground station 2 or the satellite station 3.

[0021] The storage unit 14 is a storage medium that stores various data, and includes a ROM (Read Only Memory), a RAM (Random Access Memory), and the like. The storage unit 14 stores programs executed by the control unit 15. For example, the storage unit 14 stores a program that causes the control unit 15 to function as a reception unit 151, a transmission unit 152, an identification unit 153, an acquisition unit 154, and a notification unit 155, and that corresponds to a function of communicating via the satellite station 3. This program has, for example, functions related to telephone calls and functions related to messenger services, but descriptions of these functions are omitted here. In addition to the storage unit built into the communication terminal 1, the storage unit 14 may also be an external storage device connected directly or via a network, or a storage unit included in a device such as a predetermined server.

[0022] The control unit 15 is, for example, a CPU (Central Processing Unit). The control unit 15 functions as the reception unit 151, the transmission unit 152, the identification unit 153, the acquisition unit 154, and the notification unit 155 by executing programs stored in the storage unit 14.

[0023] The reception unit 151 receives data transmission requests from the user via the operation unit 11. Specifically, the communication terminal 1 receives data transmission requests when it is not connected to the server etc. via the ground station 2, but is connected to the server etc. via the satellite station 3.

[0024] The transmitting unit 152 transmits data to the server or other communication destination via the satellite station 3 in response to the receiving unit 151 receiving a data transmission request. However, depending on the location of the satellite station 3, data may not be transmitted if the communication quality of the communication terminal 1 with the satellite station 3 is poor or if radio waves cannot reach it.

[0025] The identification unit 153 identifies the amount of data corresponding to the transmission request received by the receiving unit 151. For example, if the transmission unit 152 attempts to transmit the data corresponding to the transmission request but is unable to transmit the data (for example, if the transmission of the data is not completed within a predetermined time), the identification unit 153 identifies the amount of data by referring to the metadata of the data.

[0026] When the receiving unit 151 receives a transmission request, and the transmitting unit 152 is unable to transmit data via the satellite station 3, the acquisition unit 154 acquires information indicating the timing at which the communication terminal 1 will be able to transmit data via the satellite station 3, based on the time change in radio wave conditions, which are the conditions of the radio waves received by the communication terminal 1 from the satellite station 3.

[0027] For example, if the acquisition unit 154 is able to communicate with the satellite station 3, it may acquire information from a predetermined server (not shown) indicating the timing at which the communication terminal 1 can transmit data via the satellite station 3. In this case, the processing performed by the identification unit 153 may also be performed by the server. The server may also provide satellite station information indicating changes in the position of the satellite station 3. If the acquisition unit 154 is able to communicate with the satellite station 3, it accesses the server that provides satellite station information indicating changes in the position of the satellite station 3, acquires the satellite station information in advance, and stores it in the storage unit 14. The satellite station information is, for example, information indicating the position of the satellite station 3 at each of multiple time points, with the position of the satellite station 3 associated with each of those points.

[0028] Furthermore, when the receiving unit 151 receives a transmission request, the acquisition unit 154 acquires terminal location information indicating the location of the communication terminal 1 if the transmission unit 152 is unable to transmit data via the satellite station 3. The acquisition unit 154 acquires terminal location information indicating the location of the communication terminal 1 by, for example, using GPS (Global Positioning System).

[0029] The acquisition unit 154 then acquires timing information based on the time change in radio wave conditions, which is the condition of the radio waves that the communication terminal 1 receives from the satellite station 3, and is determined based on the change in the position of the satellite station 3 indicated by the satellite station information stored in the storage unit 14 and the position of the communication terminal 1 indicated by the acquired terminal position information.

[0030] For example, the memory unit 14 stores information for calculating radio wave strength based on the distance between the satellite station 3 and the communication terminal 1. The information for calculating radio wave strength is, for example, a table that associates the distance between the satellite station 3 and the communication terminal 1 with the strength of the radio waves received from the satellite station 3 at the location of the communication terminal 1, or a function for calculating radio wave strength based on the distance between the satellite station 3 and the communication terminal 1.

[0031] The acquisition unit 154 determines the distance between the satellite station 3 and the communication terminal 1 at each time point from the current time to a predetermined time (e.g., 1 hour) later, based on the change in the position of the satellite station 3 indicated by the satellite station information and the position of the communication terminal 1 indicated by the acquired terminal position information. Then, based on the radio wave strength calculation information and the distance between the satellite station 3 and the communication terminal 1 at each time point, the acquisition unit 154 determines the radio wave strength of the radio waves received from the satellite station 3 at the location of the communication terminal 1 at each time point, thereby determining the time change in radio wave conditions at each time point.

[0032] The acquisition unit 154 acquires information indicating the timing at which data can be transmitted by identifying the timing at which data can be transmitted based on the time changes in radio wave conditions at each identified time. For example, the acquisition unit 154 identifies the timing at which data can be transmitted by identifying the time at which the radio wave intensity received from the satellite station 3 at the location of the communication terminal 1 exceeds a predetermined threshold.

[0033] Here, the acquisition unit 154 may acquire timing information by generating timing information based on the amount of data identified by the identification unit 153 and the time change in the radio wave conditions received from the satellite station 3. That is, the acquisition unit 154 may determine a predetermined threshold based on the amount of data and identify the time when the radio wave intensity received from the satellite station 3 at the location of the communication terminal 1 exceeds the determined predetermined threshold, thereby identifying the timing when data can be transmitted. In this way, the communication terminal 1 can accurately identify the timing when data can be transmitted according to the amount of data.

[0034] Furthermore, if the communication at satellite station 3 is under load, even if the distance between the location of satellite station 3 and the location of communication terminal 1, as indicated by the satellite station information, is the same as the distance when there is no load, it may not be possible to transmit the same amount of data. For this reason, the acquisition unit 154 acquires timing information based on the number of other communication terminals connected to satellite station 3 and the time change in the radio wave conditions received from satellite station 3. In this case, the acquisition unit 154 acquires connection count information from satellite station 3, indicating the number of other communication terminals connected to satellite station 3, at predetermined time intervals.

[0035] The acquisition unit 154 determines a predetermined threshold based on the number of other communication terminals connected to the satellite station 3, as indicated by the latest connection count information. For example, threshold calculation information showing the relationship between the number of other communication terminals and the predetermined threshold is stored in the storage unit 14 in advance, and the acquisition unit 154 determines the predetermined threshold based on the threshold calculation information and the number of other communication terminals connected to the satellite station 3, as indicated by the latest connection count information. The acquisition unit 154 may then identify the timing at which data can be transmitted by identifying the time when the signal strength of the radio waves received from the satellite station 3 at the location of the communication terminal 1 exceeds the determined predetermined threshold. In this way, the communication terminal 1 can accurately identify the timing at which data can be transmitted in response to the congestion status of communications at the satellite station 3.

[0036] Furthermore, the acquisition unit 154 acquires information indicating the timing at which the communication terminal 1 will be able to transmit data via the satellite station 3 when the receiving unit 151 has received a transmission request but the transmission unit 152 has been unable to transmit the data via the satellite station 3, but is not limited to this. The acquisition unit 154 may also acquire information indicating the timing when the receiving unit 151 has received a transmission request but has been unable to transmit at least a portion of the data corresponding to the transmission request via the satellite station 3. In this way, even if the communication terminal 1 has been unable to transmit at least a portion of the data corresponding to the transmission request, the communication terminal 1 can notify the user of the timing at which it will be able to transmit data via the satellite station 3.

[0037] The notification unit 155 notifies the user of instructions regarding data transmission based on information indicating the timing of acquisition by the acquisition unit 154. For example, the notification unit 155 displays instructions on the display unit 12 that include a message indicating that the data corresponding to the transmission request could not be transmitted, and a message indicating the timing of acquisition by the acquisition unit 154.

[0038] Figure 3 shows an example of how information regarding data transmission is displayed on the display unit 12. In Figure 3, it can be seen that a message indicating that the data corresponding to the transmission request could not be transmitted is displayed, along with a message indicating the acquisition time: "It will take 5 minutes for the satellite to approach and enable data transmission." This allows the user to understand the time until data can be transmitted, thereby improving user convenience.

[0039] In addition, the notification unit 155 may display a message on the display unit 12 indicating that the data will be automatically resent, such as "We will resend the data immediately," without indicating the timing of acquisition. Alternatively, the notification unit 155 may display a message on the display unit 12 indicating that the data will be resent, such as "We will resend it in 5 minutes," while indicating the timing of acquisition. In this case, the transmission unit 152 determines the timing of data resending based on the information indicating the timing acquired by the acquisition unit 154, and resends the data to the server or other communication destination based on the determined resending timing.

[0040] If data cannot be transmitted via satellite station 3, it may be possible to transmit the data by reducing the amount of data. In this case, the identification unit 153 may determine the amount of data that communication terminal 1 can transmit via satellite station 3 at the present time, based on the radio wave conditions of the radio waves that communication terminal 1 receives from satellite station 3. For example, information showing the relationship between the amount of data and the minimum radio wave intensity at which that amount of data can be transmitted may be stored in the storage unit 14, and the identification unit 153 may refer to this information to determine the amount of data that corresponds to the radio wave intensity of the radio waves that communication terminal 1 receives from satellite station 3 as the amount of data that communication terminal 1 can transmit via satellite station 3 at the present time.

[0041] The notification unit 155 then notifies the communication terminal 1 of the amount of data that it can transmit via the satellite station 3 at the present time, as identified by the identification unit 153. For example, the notification unit 155 displays information on the display unit 12 indicating the amount of data that the communication terminal 1 can transmit via the satellite station 3 at the present time. The notification unit 155 may also display a message on the display unit 12 indicating that data can be transmitted at the present time if the data is of a data type corresponding to the amount of data that the communication terminal 1 can transmit via the satellite station 3 at the present time.

[0042] [Processing flow in communication terminal 1] Next, we will explain the processing flow in communication terminal 1. Figure 4 is a flowchart showing an example of the processing flow in communication terminal 1. At the start of this flowchart, communication terminal 1 is not connected to the server, etc., as the data transmission destination via ground station 2, but is connected to the server, etc., via satellite station 3.

[0043] First, the reception unit 151 receives a data transmission request from the user via the satellite station 3 (S1). Next, the transmission unit 152 transmits the data to the server or other communication destination via the satellite station 3 (S2).

[0044] Next, the acquisition unit 154 determines whether the transmission unit 152 was able to transmit data via the satellite station 3 (S3). If the acquisition unit 154 determines that the data transmission was successful (YES in S3), it moves to S4; if it determines that the data transmission was not successful (NO in S3), it moves to S5. In S4, the notification unit 155 notifies the user of the completion of data transmission by displaying a message on the display unit 12 indicating that the data transmission has been completed.

[0045] In S5, the acquisition unit 154 acquires satellite station information indicating the change in the position of satellite station 3, which it had previously acquired and stored in the storage unit 14, thereby identifying the time change in radio wave conditions, which are the conditions of the radio waves received by the communication terminal 1 from satellite station 3. Subsequently, the acquisition unit 154 identifies the position of the communication terminal 1 by acquiring terminal position information indicating the position of the communication terminal 1 (S6). Note that the processes in S5 and S6 may be executed in different orders or in parallel.

[0046] Next, the acquisition unit 154 acquires information indicating the timing at which data can be transmitted, based on the time change of the identified radio wave conditions and the location of the communication terminal 1 (S7). Subsequently, the notification unit 155 notifies the user of instructions regarding data transmission based on the timing information acquired by the acquisition unit 154 (S8).

[0047] [Differentiation] In the above-described embodiment, the transmitting unit 152 simply transmitted data to the server or other communication destination via the satellite station 3 in response to the receiving unit 151 receiving a data transmission request, but it is not limited to this.

[0048] When the transmitting unit 152 receives a transmission request, if it is unable to transmit the data corresponding to the transmission request via the satellite station 3, it may identify data of high urgency contained in the data. For example, the transmitting unit 152 identifies data of high urgency for each of the multiple data types based on the importance criteria set for each type. For example, if the data type is text data, it identifies text data containing keywords such as "help" or "cannot move" from among multiple text data as data of high urgency. The transmitting unit 152 then prioritizes transmitting the identified data of high urgency via the satellite station 3. In this way, the communication terminal 1 can quickly inform the recipient of the data that it is of high urgency.

[0049] Furthermore, the transmitting unit 152 may identify the remaining battery capacity of the communication terminal 1, and if the identified remaining capacity is below a predetermined threshold, it may prioritize the transmission of data of high urgency. In this way, the communication terminal 1 can prevent the recipient from being unable to receive information about the urgency of the data due to the battery running out.

[0050] Furthermore, the acquisition unit 154 may acquire information indicating changes in the area from which the data to be transmitted can be sent, as information indicating the timing when the communication terminal 1 becomes capable of transmitting data via the satellite station 3. For example, the acquisition unit 154 may acquire video information showing the location of the communication terminal 1 and the area from which the data to be transmitted can be sent at each of several time points, as information indicating the timing. The notification unit 155 may then display the video information showing the area from which the data to be transmitted can be sent on the display unit 12 as information indicating the timing. In this way, the user can intuitively grasp the timing when the data will become capable of being transmitted.

[0051] [Effects of this embodiment] As explained above, when communication terminal 1 is not connected via ground station 2 but is connected via satellite station 3, it accepts a data transmission request via satellite station 3. If data transmission via satellite station 3 is not possible, communication terminal 1 acquires information indicating the timing at which it will be able to transmit data via satellite station 3, based on the time change in radio wave conditions, which are the conditions of the radio waves received by communication terminal 1 from satellite station 3. Based on this timing information, communication terminal 1 notifies the user of guidance regarding data transmission. In this way, communication terminal 1 can improve user convenience when communicating via satellite station 3.

[0052] Furthermore, this invention will make it possible to contribute to Goal 9 of the United Nations-led Sustainable Development Goals (SDGs), "Build resilient infrastructure, promote inclusive and sustainable industrialization and foster innovation."

[0053] Although the present invention has been described above using embodiments, the technical scope of the present invention is not limited to the scope described in the above embodiments, and various modifications and changes are possible within the scope of its gist. For example, all or part of the apparatus can be configured by functionally or physically distributing and integrating in any unit. Furthermore, new embodiments resulting from any combination of multiple embodiments are also included in the embodiments of the present invention. The effects of the new embodiments resulting from the combinations are combined with the effects of the original embodiments. [Explanation of Symbols]
